System and method for promoting and tracking physical activity among a participating group of individuals

ABSTRACT

A system and method of tracking physical activity of a person in order to help motivate that person to add more exercise to their lives. Each participant is provided a motion sensor that detects forces incurred by the participant. The motion sensor creates electronic data that corresponds to the forces detected. The data is analyzed to determine whether or not exercise has been performed. The analysis can also determine the type of exercise performed, when the exercise was performed, and the duration of the exercise performed.

BACKGROUND

1. Field

In general, the present invention relates to systems and methods thatare used to track the health and wellbeing of people within a targetedgroup. More particularly, the present invention relates to systems andmethods that utilize interactive software to both promote and trackphysical activity among participants in the targeted group.

2. Description of the Background

It is a well-established fact that people generally live longer,healthier lives if they exercise regularly. It is also awell-established fact that people are more likely to start and continuean exercise program if they have peers and friends that are alsoparticipating in that exercise program. Recognizing the above statedfacts, many companies have developed employee exercise programs. Thehope is that these programs would lead to healthier employees andhealthier employees, who would use less sick days and have lowerhealthcare costs. By offering such exercise programs at work, it ishoped that employees would exercise with peers and would benefit fromthe support of peers.

Difficulties develop, however, when the management of a company tries todevelop exercise programs for their employees. The problem is that notall people enjoy the same types of exercise. As such, a company gym mayonly appeal to some employees, while a company softball team may appealto others. Recognizing that different people like different things,exercise programs have been developed that are highly flexible to fitthe varied needs and wants of a company's employees. In such exerciseprograms, the management of a company does not concern itself with whatexercise is being performed. Rather, the company just monitors whetherexercise is being performed and offers incentives to employees tocontinue exercising.

The most common way that companies monitor whether or not an employee isperforming exercise is to provide the employees with interactivecomputer software. Using the software, an employee can enter whatexercise has been performed. This information is then stored in adatabase for access by the company. Such exercise monitoring softwaresystems are exemplified by U.S. Patent Application Publication No.2006/0287883 to Turgis, entitled Interactive Internet Supported HealthAnd Fitness Management System; U.S. Patent Application Publication No.2007/0072154 to Kaufman, entitled Lifesytle Coach Behavior ModificationSystem; and U.S. Patent Application Publication No. 2007/0100595 toEarles, entitled Behavior Monitoring And Reinforcement System andMethod.

The problem associated with such prior art exercise monitoring softwaresystems is that the systems require that an individual manually inputdata into a computer to inform the computer of what exercise has beenperformed. Since many of these systems provide rewards for exercise,there is a perverse incentive for people to lie or exaggerate aboutexercising in order to receive the reward. Furthermore, people mayquickly grow tired of tasks in which they are not interested. Employeesthat must voluntarily enter and log their daily exercise routines mayquickly develop user fatigue. Employees may forget to enter data dailyand when they do enter data, that data may contain guesses andinaccurate remembrances of days past.

A need therefore exists for an exercise system that passively andaccurately monitors the amount of exercise performed by an individual,thereby reducing cheating and user fatigue. A need also exists for anexercise system where all exercises are automatically reduced tocomparable caloric expenditure units, thereby putting all exercises on acomparable basis for use in challenges and competitions. These needs aremet by the herein described systems and methods.

SUMMARY

The present disclosure describes apparatus, systems, and methods fortracking physical activity of participants in an exercise program inorder to help motivate them to add more exercise to their lives. Eachparticipant is provided with a motion sensor that detects motionexperienced by the participant. The motion sensor creates electronicdata that corresponds to the motions detected. The motion detector isworn or carried by the participant somewhere on the body when theparticipant is exercising, and also when the participant is notexercising.

The motion sensor has the ability to passively transmit the data itcollects. The data is analyzed. During the analysis of the data, it canbe determined whether or not exercise has been performed. The analysiscan also determine the type of exercise performed, when the exercise wasperformed, and the duration of the exercise performed.

The exercise of each participant can be converted into a caloricequivalent, and thence to a caloric expenditure unit for a preselectedspecific type of exercise. In this manner, the exercise equivalents ofeach participants' activities can be compared and applied to commonexercise goals or exercise competitions. If an exercise goal is achievedby a participant, that participant is rewarded, such as with rewardpoints in an amount proportionate to the difficulty of achieving thatexercise goal. The reward points can be used as payment, for example,for goods and services that promote a healthy lifestyle.

DETAILED DESCRIPTION

Although the herein described systems and methods can be used by manydifferent user groups, such as schools, health clubs, or a community ofregistered online users, the embodiment illustrated shows the systembeing used by an employer to promote exercise among its employees. Thisembodiment is selected in order to set forth the best mode contemplatedfor the invention. The illustrated embodiment, however, is merelyexemplary, and not limiting. The scope of the invention is determined bythe appended claims.

Referring to FIG. 1, a portion of a traditional office 10 is shown inwhich employees work. The employees have computers 12 that are connectedthrough a network 14 to a remote systems computer 16, such as a servercomputer. The network 14 can be private, or may be connected to theInternet.

Each employee is provided with a monitoring unit 20. The monitoring unit20 is carried by or worn on the body of the employee. In an embodiment,the monitoring unit 20 is connected to the shoe 22 of the employee.However, the monitoring unit 20 can also be connected to a sock,watchstrap, belt, lanyard, or other arrangement, such as on a limb orwaist of the employee. As will later be explained in more detail, themonitoring unit 20 records data corresponding to motion and forcesexperienced by the monitoring unit 20 in a given time period. The datacan be used to determine whether or not exercise has occurred. The datacan also be used to determine the type of exercise performed, when thatexercise was performed, and the duration of the exercising.

In the office 10, at least one transceiver 24 is provided. Thetransceiver 24 transmits an activation signal 26 that is received by anymonitoring unit 20 within range. Once a monitoring unit 20 receives anactivation signal 26, it transmits its stored data to the transceiver 24along with an identifier code for the employee. The transceiver 24receives both the identifier code and the transmitted data. Thatinformation is then forwarded to the remote system computer 16 via thesame computer network 14.

The downloading of data from the monitoring unit 20 to the systemcomputer 16 happens automatically each time an employee comes into theoffice 10. As such, the data transfer is passive, needing no effort fromthe employee. The employee need only remember to connect the monitoringunit 20 to a shoe or similar article of clothing being worn.

The system computer 16 utilizes the data from each employee to trackwhat exercise has been performed by the employee and when. Many types ofexercise can be identified by the system computer 16 through analysis ofthe type of data that is received. For instance, walking and running areeasily identifiable. Other types of exercise can be identified asexercise, but the specific exercise may not be discernable. Forinstance, the data produced from playing tennis is nearly identical tothe data produced from playing dodge ball. However, dodge ball may notburn the same amount of calories as does tennis.

When an employee logs onto his/her office computer 12, the employee maybe actively prompted with a message that indicates the exercise systemhas received new data. Otherwise, the system may be passive and wait foran employee to log onto the exercise system. Once interacting with theexercise system, the employee can recall data in many formats to showwhen exercise was performed, what exercise was performed, and for howlong. As will later be explained, the data can also be applied toselected exercise challenges and competitions.

If the exercise system has received data that it cannot positivelyidentify, then the employee is prompted to identify the exercise. Theemployee is reminded of when the exercise was performed and for howlong. The employee then is provided with a list of exercises from whichto choose. The employee selects the exercise that best described theactivity performed. The system computer 16 then has a complete set ofdata corresponding to the exercise activities of the employee.

To help motivate the employee, the exercise system 10 presentschallenges and competitions to the employee. The system computer 16 thenapplies all exercise data to those challenges and competitions, in amanner later explained.

Referring to FIG. 2, a schematic of a monitoring unit 20 is shown. Eachmonitoring unit 20 contains at least one accelerometer 28. Theaccelerometers 28 are preferably micro-electromechanical systems (MEMS),however other technologies can be used. The accelerometers 28 measurechanges in acceleration in different orientation planes and convert thatinformation into corresponding electronic signals. Within the monitoringunit 20, a clock 30 is provided. The clock 30 creates a time code signalthat is coupled to each electronic signal produced by the accelerometers28. The combined signals are stored in a memory 32 as data signals.

Each monitoring unit 20 has its own identification code 34 thatidentifies the monitoring unit 20. Each monitoring unit 20 also has areceiver 36 for receiving the activation signal (26, FIG. 1) and atransmitter 38 for transmitting both the data signals and theidentification code 34. Suitable monitoring units 20 that can be adaptedfor use by this invention are manufactured by Fitlinxx, Inc. of Norwalk,Conn.

Referring now to FIG. 3 in conjunction with FIG. 1, the operationalmethodology of the system is described. As is indicated by Block 40,each participating employee is assigned an account number for accessingthe system computer 16. Furthermore, each participating employees isprovided with at least one monitoring unit 20. See Block 42. An employeemay be given more than one monitoring unit 20. In this manner, theemployee can attach a monitoring unit 20 to each of the sets of shoeshe/she commonly wears. Within the system computer 16, the identificationcode 34 for each monitoring unit 20 given to an employee is assigned tothe account for that employee.

Once an employee has set up an account, the employee is provided with achoice of exercise challenges from which to choose. See Block 44. Forinstance, one challenge may be a virtual hike. An employee, using theirnetwork computer 12, may select a geographical area, such asPennsylvania, France, Kenya or the like. The systems computer 16 willthen generate a virtual hiking tour. The systems computer 16 will thenindicate how many steps are required to complete the virtual tour. Forexample, it may be 456,789 steps. The challenge, then, becomes for theemployee to walk 456,789 steps. Each time the employee downloads data tothe system computer 16, the data is converted to steps, if necessary,and applied to the challenge. The systems computer 16 may providedifferent images of different landmarks in the selected geographicalarea as data is applied to the challenge.

Other challenges may also be provided. For example, one employee mayenter into direct competition with other employees to complete a statedamount of exercise in a stated amount of time.

Rewards may be provided to people who accomplish or win challenges. Thenature of the rewards is later described in conjunction with FIG. 4.

As is indicated by Block 46, once an employee is entered into achallenge, the employee is left alone to live his/her life. It is hopedthat the presence of the challenge and a potential reward or completingthe challenge will entice the employee to exercise wherever and wheneverthey can. For instance, an employee may park farther away from work inorder to walk a little more. The employee may take the stairs instead ofthe elevator. All of these little exercises are automatically recordedand are applied toward the employee's challenge.

The exercise data generated by an employee is stored until the employeetransfers data to the system computer 16. This can be done automaticallyby having the employee come within range of an office transceiver 24.However, if desired, an employee can connect the monitoring unit 20directly to a computer at their home or office, using a standard USBconnection cable. This is very useful for people who 13 work some daysat home or travel often as part of their job. Once the exercise data isdownloaded, the data is analyzed by the system computer 16. See Block48. First, the data is identified according to the types of exercisepreformed the data. Different exercises produce different types of data.Since the monitoring unit 20 contains accelerometers, the data gatheredis analog in nature. Walking produces specific signals within theaccelerometers at repeating intervals. A walking signal isstraightforward to identify. Running creates greater accelerometersignals at faster intervals and is easy to identify. The signal profilesof numerous exercises are known. For instance, the signals generated bybicycle riding, swimming, and climbing stairs are readily identified.However, the signals generated by some other exercises can be identifiedas exercise, but cannot be precisely identified as to the type ofexercise. For example, tennis and dodge ball create nearly identicalsignals from a monitor unit 20 worn on the foot.

As is indicated by Block 50 and Block 52, when a signal containsexercise data that cannot be specifically identified, the systemcomputer 16 prompts the employee the next time the user logs onto thesystem. In the prompt, the employee is provided with a choice ofexercises from which to choose. The employee is reminded of when theexercise occurred and for how long the exercise lasted. The user thenselects the exercise that best fits the exercise that was recorded.

In some circumstances, the monitoring unit 20 may fail to recognize someexercise that has occurred. For instance, if an employee is wearing themonitoring unit on their foot and then goes canoeing, the monitoringunit 20 many not record any exercise even though strenuous exercise isoccurring. In such situations, an employee does have the option ofmanually entering a specific exercise for a specific period of time.However, the exercise selected cannot be contrary to the data signalsreceived for that period. If the selected exercise does not match thedata signal, it may be assumed that the employee is lying orexaggerating and the data signal may be ignored by the system computer16.

Once the system computer 16 has all the exercise data for a specificperiod of time, the system computer 16 converts the exercise data tothat of the challenge exercise. See Block 54. The challenge exercise isthe exercise selected by the employee when initially selecting achallenge, as indicated back in Block 44. For instance, if the selectedchallenge is a virtual hike, as has been previously suggested, then allexercise data is converted into walking steps. However, if the selectedchallenge were a virtual marathon, then all exercise data is convertedinto running steps. Conversion is conducted by a determination ofcaloric expenditure equivalency. For example, if the selected challengeexercise is walking and walking is assigned a caloric expenditure of 250calories per mile, then swimming for fifteen minutes is converted to onemile of walking This is because swimming for fifteen minutes also burns250 calories, which is a caloric equivalent of one mile.

Once all the exercise data is converted into its challenge exerciseequivalent, then the data is applied to the selected challenge. SeeBlock 56. Accordingly, an employee who rides a bicycle to work and playsbasketball, may quickly complete a walking challenge without everintentionally walking for exercise.

By converting all recorded exercise data into its challenge exerciseequivalency, all employees can compete toward the same goal even thoughthey exercise in different ways. Also, various employees can competedirectly with each other, even though each employee exercises in adifferent way.

Referring to FIG. 4, the rewards portion of the method of operation canbe outlined. As has been previously stated, an employee selects achallenge in which to particip ate. An employer may elect to providerewards to the employee if the challenge is met. The rewards may befinancial or work related, such as an extra vacation day. However, aunique rewards program is preferred.

As is indicated by Block 60 and Block 62, if an employee successfullycompletes an exercise challenge, then the employee is assigned a numberof virtual reward points to his/her account. The number of reward pointsto be granted is directly dependent upon the difficulty of the exercisechallenge that has been completed.

The administrator of the present invention system may enter intocontracts with a variety of health promoting venues. The venues mayinclude health clubs, sports clubs, sports equipment retails, vitaminretails, and the like. In these contracts, the venue companies agree toaccept the virtual points awarded employees in exchange for somepredetermined compensation. A list of participating companies isprovided to each employee. See Block 64. The employee can then spendhis/her reward points by buying the goods or services from the variousparticipating companies. See Block 66.

By restricting the venues in which the reward points can be spent, eachemployee is provided a significant but limited choice. However, all thechoices are beneficial to the health and well-being of the employee. Itis therefore hoped that an employee's exercise will beself-perpetuating. That is, an employee earns reward points byexercising in a gym and the reward points help pay for membership inthat gym. Otherwise, an employee earns reward points by playing a sportand the reward points pay for the equipment used to play that sport.

After an employee uses the present invention system for a period oftime, a great deal of information is gathered concerning when and how aparticular employee exercises. This information is formatted andprovided to the employee for the benefit of the employee. Referring toFIG. 5, a graph 70 is shown that shows activities plotted by time andcalories burned during the course of one day. The graph 70 shows onlyone of many ways the data can be formatted. However, when formatted asillustrated, an employee can see when they are exercising the most andwhen they are exercising the least. This may encourage employees to takethe stairs or otherwise do some exercise during non-traditional hours.
